Structural analysis of the core region of the lipopolysaccharides from eight serotypes of Klebsiella pneumoniae Original Research Article

The core regions of the lipopolysaccharides (LPS) from Klebsiella pneumoniae serotypes O1, O2a, O2a,c, O3, O4, O5, O8, and O12 were analysed using NMR spectroscopy, ESI-MS spectroscopy, and chemical methods. All the LPSs had similar core structures, as shown below, differing only in the number and position of β-d-galact
